Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1921 edition. Excerpt: ... the face, nose and cheeks, and a red fundus reflex can be perceived in the eyes, tooth by the surgeon and by patient himself. The intensity of the glow varies in different individuals; in thin-boned, fair persons, the illumination is bright; in stout, large-boned, dark people, especially if the palate is narrow or highly-arched, or the nasal passages obstructed, the illumination is feeble or dull. A light of low brilliancy is therefore used for thin people, and a light of high brilliancy for stout, dark people. As sinus disease is frequently unilateral, we can compare one side of the face with the other. The particular areas of luminosity to be observed are those crescents of red light lying along the inferior margin of the bony orbit, and known as the "infra-orbital crescents." When this crescent is present, the antrum transillumination is called " clear "; when it is absent, antrum transillumination is "dull." The amount of light traversing the anterior wall of the antrum and showing on the cheek is very variable, but almost always it is much darker there than at the lower edge of the orbit. Conclusions.--When the antrum transillumination is equally clear on both sides, the antra are empty and probably healthy; when dull, the antrum is filled more or less--it may be with pus, polypi, or a solid growth. The following table summarizes the conditions which influence transillumination (Brown Kelly): A. Brilliancy is favoured by--1. Cysts with clear contents, distending and thinning the antral walls. B. Brilliancy is decreased by--1. Collections of mucus, blood, or pus in the antrum; 2. Inflammatory and polypoid thickening? of the antral walls; and 3. Tumours in the antrum. Fallacies.--If the pus in the antrum...show more
